Applicationled May 11, 1916.

To all 'whom t may conce/ra.' f

lBe it known that I, FREDERICK H. BARZ, a citizen of the United States of America, residing at Ventura, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Hay- Distributers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to hay forks, and has for its object, the production of an efiicient hay fork for facilitating the distribution of hay upon a mound.

Another object of this invention is the production of an efcient means whereby the tipping of the hay distributing fork will be regulated to alternately drop the hay upon opposite sides of the hay fork.

IVith this and other objects in view, this invention consists of certain novel construe- Y tions, combinations, and arrangementof parts, as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a side elevation of the tipping fork as applied to a barn or other place of storage for hay.

Fig. 2 is a side elevation of the lower portion of the supporting standard showing the fork partially dumped toward one side of the standard.

Fig. 3 is an enlarged transverse longitudinal section through the supporting standard showing the tripping trigger for the hay distributing fork in top plan.

Fig. i is a section through the trigger and supporting means therefor.

Fig. 5 is a perspective view of the pivotally mounted trigger.

Fig. 6 is a perspective view of the latch device for holding the trigger in a set position.

one of the hangers for holding the fork in a set position upon `the track.

Fig. 3 is a vertical section through the truss of the hanger showing an end view of the front hanger member.

Fig. 9 is a detail perspective of the clamping plate used in connection with the hanger plate shown in Fig. 7 y

Referring to the drawings by numerals, 1t will be seen that the present device is susceptible of being used in a barn or other place of storage for hay, and within the barn or other place of storage is carried a track 1,

which preferably extends longitudinally of the barn. A hanger is suspended from the track 1', and comprises aV forward hanger member 2 and a rear hanger member 3. The forward hanger member 2, comprises a Ypair of parallel plates t provided with overhanging ends 5. A roller 6, is journaled between the parallel plates 4 and over this roller travels the shifting cable 7. The forward hanger 2 and the rear hanger 3 are connected by means of a truss member 8 being twisted at its center portion to form a support for the main supporting standard 9.

The rear hanger 3 comprises a pair of parallel plates 10 which are bent inwardly at their lower ends as indicated at 11 for firmly clamping around the truss member 8. The upper Vends of the parallel members 10 are bent inwardly as indicated at 12 overhanging the track 1. The bracket 13 is adjustably secured to one of the side members 10 and through this bracket 13 passes an adjustable rod 14 which is threaded at its upper end to facilitate the adjustment of the rod 14 within the Vbracket 13. A clamping' plate 15 is also provided with a rounded neck portion 18 intermediate its ends for traveling' in the longitudinally extending slot 19 formed in the opposite parallel portions 10. rIhe projecting' end 20 of the clamping plate 15 overhangs the bracket 13 so as to be readily engaged by the upper end of the rod 14E. rIhis clamping plate 15 passes under the track 1, and it will be seen that this clamping plate 15 may be firmly forced into engagement with the track 1, to hold the hay distributing fork in a set position upon the track 1. The reduced portion 16 of the plate 15-is held in the aperture 17 by means of the vertically sliding angle plate 21 which angle plate 21 is provided with an angle foot 22 for facilitating the sliding of the plate 21 upon one of the parallel members 10. rilhe plate 21 is firmly held in engagement with one of the side members 10 by means of the bolt 23.

The rod 14 ispreferably long enough so as to allow the hay distributing fork to be locked upon the track 1 at the desired place by the operator of the hay distributing fork.

The main supporting rod 9 carries at its lower end a pair of spaced brackets or bracket members 24 which members constitute a support for the anchoring rod 25.

The anchoring rod 25 is provided with angular end 26, which overhangs the upper Y bracket 24 so as to limit. the downward movement of the anchoring rod 25. The upper bracket 24 is provided with-a folded end 27 through which the main supporting rod 9 passes, and this folded end 27 assists in holding the anchoring rod 25 in its correct position. Ahay fork supporting bracket 28 is carried by the main supporting rod 9-and is i rotatably mounted thereon. A collar 29 is of a bolt 36. vThe lowerend of the link 35 is .pivotably connected to a vertically eX- tending` bolt 37 which bolt has its lower head-portion 38 secured in the folded end 39 ofgthe bracket 40 carried by the lower en ofthe mainsupporting rod 9. A trigger-rod 41 is carried by the bolt 37 as is illustrated in Fig. 2 anda coil spring 42 is `wound around the bolt37 and engages the rear end of therod 41 asis clearly illustrated in Figs. 1-- ,2,-v and The trigger-bar or rod 41 is preferably reduced asindicated at-,41Pwhen passing. through the bolt 37. The .free endsof the spring 42 are'hooked around the lower end of the supporting rod 9 vas illustrated clearlyinFig. 1'. A triggerlatch .43. ispivotably secured to the rod 41- so. as to yhave a vertical swinging movement and vthis latch is of a substantially U-shaped structure having a bifurcatedend 44 which straddles the trigger-rod 41. in such a manner. as to allow thelatch 43 toswingjup-YV wardly out of. engagement with the main supporting rod.9 as abovev cited.y

This latch member 43 is Vadapted to be swung upon the trigger-rod 41 and controls the dumping of'the'hay fork.` A locking frame 45 is pivotallyy secured to the triggerrod 41 by means of a pivot pin 46 and this locking frame 45 is provided with a projecting end 47 'which end is adapted to engage the notched ends 48of the latch 43 and hold thelatch in a vertical position as illustrated clearly in Fig. 4'.V The projecting end 47 is provided with a downwardly extending spur 49 which extends transversely of theiprojectingend 47.

A spring 5() is carried by the trigger-rod 41 and is wound around the transversely extending pin 51 of the frame 45. The outer end 52 of the spring 50 is adapted to engage the trigger 43 and normally urge the same 'sition as toengage the spur 49 and force the proj ectingend 47 of the frame 45 out of e'ngagement with the trigger 43 thereby causing the trigger 43to vbethrown downwardly by l.means ofthe spring 52. The finger 53 eX- tendsV on a; -linegwith the bracket g4-0; .s o as 'to bein aneXaCtQentral postonireletve rod i9.- whereby. the spur 49Wil1 besoin/yengaged by the linger 53 when the fork 30 assumes its normal horizontal position; .Y A pair of laterally extending'- upwardly-y curved arms 54 are carriedby thestandard 9 adjacentthe point which is "adapted-to be engaged by; the. A trigger 43 and these arms are formed on thearc ofa circle "so A`a s toallow the trigger 4,3 to travelthereon and-loe forced toa Svertical position asis illustrated in dottedlinesin F ig. 1 thereby causing theY locking frame 45 to hold the trigger 43 in a vertical position untilgthe fork assumes its normal horizontal position. I

Vhen the latch .43 is positioned in` the manner, illustrated in Fig 3, the fork will' dumptoward the right as soon as the weight of afload of hay ,hasbeen placed thereon; Vhen the latch 43 is placed upontheopposite side of. the main. supportingrod 9 so as to `eXtendin a horizontalpositions; the fork will dump inthe opposite direction or A{to-i100 ward the left of the supporting .ro d 9a .Owing to the fact 'tha tfasV the fork ,dumpsitoward oney vdire einen-, .the latch 43 will be locked. in a.v4 vertical position,` th'e j :latch '.43 will be caused to drop upon the opposite side 105 of the` supportingrod9 d ue to they momentum which the fork will gather whenreturning t toits. normal .horizontal position. This is caused by the finger 53 engaging the l spur 49 and releasing the projecting `end 110 47 from the latch 43 .whereupon-the latch V43 y will be thrownto a horizontal position by means of the spring 52. lt should belunder-V stood that the latch 43 willfnotbegin to drop to a horizontal position-until'after the lockf 115 ing frame 45 has passed the linger 53 and"l this-will causer the latch 43 VtoA drop upon opposite sides rof the supporting rod 9 at alternate times. v Y

A spring supporting collari55 is carried 120 by the main supporting rodg9, and this collar is provided with agdownwardlyextending hook 56, which engages the upper end ofthe spring 57. This spring 57 engages the collar 58 carried by one of the teeth of the hay ,125 distributing fork and this spring 57 returns the fork to its normal position after the hay vhas beenV removed or distributed therefrom?Y The operation of the device is as follows:

weight of Ltheload tends tofcause the fork to swingV downwardly on the pivot 32, against the tension 4of the spring 47. The fork 'however in its downward movement, is forced to swing to one side by the rod 35 which rotates about the axis of the bolt 37 as a center, while the fork swings about the support 9 as a center. The spring 42 tends to prevent the turning of the bolt 37 and hence the rotation of the fork. Said springs are sutliciently strong to prevent rotation under the weight of the forli alone, but will allow the fork to rotate under the additional weight of a load to be placed thereon. The latch 43 by being raised to a vertical position upon each swing of the fork 30, will be caused to alternately drop upon opposite sides of the supporting rod 9 due to the fact that the finger 53 will release the trigger 43 from the frame 45 as the trigger bar 41 is passing the center of the rod 9.

From the foregoing description it will be seen that a very simple and elicient means has been produced for causing the hay fork to automatically and alternately dump in opposite directions.

The present invention is an improvement upon my previous application bearing Serial Number 701099, filed June 1st, 1912, and allowed November 28th, 1913. The special improvements in the present invention over my previous invention resides in the means for automatically and alternately dumping the fork in opposite directions.

It, of course, should be understood that the spring 52 is necessarily formed of line spring wire as shown clearly in Fig. 1 of the drawing. The spring 52 is, however, shown slightly exaggerated in size in Fig. 4 but it is desired to point out that this spring is necessarily formed of iine spring wire but is only wound around the pin 51 with one convolution in order that the frame 45 may operate. rlhis construction of the spring 52 will permit sufficient yielding movement for the frame 45 to accomplish the desired result.
